Chromosomal Aberrations
Chromosomal aberrations are abnormalities in the structure or number of chromosomes and are often responsible for genetic disorders. For more than a century, scientists have be...

Chromosomal Banding
A chromosome banding pattern is comprised of alternating light and dark stripes, or bands, that appear along its length after being stained with a dye. A unique banding pattern is ...

Chromosomal Theory of Inheritance
The chromosomal theory of inheritance is the idea that genes, the units of heredity, are physical in nature and are found in the chromosomes. The theory arose at the ...

Chromosome, Eukaryotic
Living organisms are divided into two broad categories based upon certain attributes of cell structure. The first category, the prokaryotes, includes bacteria and blue-green alg...

Chromosome, Prokaryotic
The bacterial or prokaryotic chromosome differs in many ways from that of the eukaryote. The term &#x0022;eukaryote&#x0022; comes from the Greek and means &#x0022;true nucleus....

Chromosome
Chromosomes are structures in the nucleus of the cell that contain the DNA or hereditary material which form genes. Genes are the commonly known units of heredity, and some may contribute t...

Chromosomes
The genetic material in plants, animals, and fungi is called deoxyribonucleic acid (DNA), a long, linear polymer that is physically organized at the microscopic level into chromosomes. Chr...

Chromosomes
Chromosomes are microscopic units containing organized genetic information, located in the nuclei of diploid and haploid cells (e.g., human somatic and sex cells), and are also present in ...
Read more

Chromosome
Chromosomes are thread-like bodies in the cell nucleus of all plants and animals that hold the genes--the blueprints of heredity. Each chromosome carries a single strand of DNA that threads...

Chromosome Mapping
Also known as cytogenetic mapping or genetic mapping, chromosome mapping is a technique used to locate particular characteristics (coded for by specific genes) on specific chromosom...

Chromosome
Chromosomes are thread-like bodies in the cell nucleus of all plants and animals that hold the genes--the blueprints of heredity. Each chromosome carries a single strand of deoxyribonucleic...

Chromosomal Mutations and Abnormalities
Chromosome abnormalities describe alterations in the normal number of chromosomes or structural problems within the chromosomes themselves. Both kinds of chromo...

Chromosome
A chromosome consists of the body's genetic material, the deoxyribonucleic acid, or DNA, along with many kinds of protein. Chromosomes contain the genes, or segments of DNA, that encode for...

Chromosome Identification and Banding
Each pair of chromosomes in the eukaryotic cell contains a unique set of genes and thus the DNA sequence is also unique for each different chromosome pair. When c...

Chromosome Mapping and Sequencing
A chromosome map describes the order of genes and other markers, and the spacing between them on the chromosome. These maps are constructed with different levels of c...

Chromosome Segregation and Rearrangement
Chromosome segregation refers to the coordinated movement of chromosomes to opposite poles of the cell during either cellular reproduction (mitosis) or the pro...

Human Artificial Chromosomes (Hac)
Human artificial chromosomes (HAC) are synthetic chromosomes that are structurally similar to normal chromosomes that, in addition to being artificially created, car...

Sister Chromatid Exchange
During the S-phase of the cell cycle, DNA is replicated and each chromosome is present in a duplicated state with the two genetically identical chromatids joined together at ...
Read more

Chromosomes, Prokaryotic
The genetic material of microorganisms, be they prokaryotic or eukaryotic, is arranged in an organized fashion. The arrangement in both cases is referred to as a chromosome.
T...
